Its easy if u can afford the pump as a unit than go for it. I replaced mine. If not, and money is tight just get the kit.
But you should list what problem ur having first. It may not even be a fuel problem.
Well the problem is when take it out I pump the bulb tight and it takes off like it should. But then after about 100 yards it bogs down and goes really slow no matter if it's at half throttle or wide open. If i sit there and pump the bulb while im going it picks up again. So im assuming it has to be the pump. Do you agree?
